Made a Wyze cam v3 holder for the Elegoo Neptune 4 Max.
I used supports with the option for supports to be "on the build plate only".
Printed with PLA
20% infill
0.2 layer height
0.4 nozzle
5mm brim on outside only (may not need but I used one)
I used a M3 x 10mm to mount through the existing hole. Just make your own threads by forcing it into the existing hole. It may be easier to make your threads before mounting it to the printer.
The author marked this model as their own original creation.
